AGETYLENE-'IGAS G EN EBATOR.

SPECIFICATION forming part of Letters Ivatent No. 680,293, dated August 13, 1901.

- Application Sled July 14, 1900.

To all whom it may concern:

Be it known thatI, DANIEL H. TEEICHLER, a citizen of the United States,residin g at Niagara Falls, in the county of N iagara and StateV of New York, have invented new and useful Improvements in Acetylene Generators, of which the following is a specification.

This invention relates to an acetylene-` generator in which the gas is generated by delivering small quantities of water u pon a charge of calcium carbid.

The objects of this invention are to improve the means whereby the generation f gas is controlled, to improve the means for purifying-the gas, to provide simple mears for regulating. or equalizing the pressure of the gas,\.to provide means whereby small charges of carbid may be used moreadvantageously, and to improve the apparatus in other respects. v

In the accompanying drawings,.con'sisting of three sheets, Figure 1 isavertical section of my improved acetylene-lamp, showing the darkening-hood'raised into its operative position. Fig. 2 is a vertical section of ythe same at right angles to Fig. 1 andshowing the. darkening-hood in, its lower inoperative Figs. 3,. 4, an'd 5 `are horizontal spectively. Fig. -6 is a fragmentary vertical section of the hood. and connecting'parts in line 6 6, Fig. 1. Fig. 7 is a vertical section of my improved acetylene-lamp, showing a construction in which the pu rifyin g-chamber is omitted. Fig. 8 isa horizontal section of the same in line 8 8, Fig. 7.

Like letters of reference refer to like parts in the several figures. v

A represents the main water-chambe which is preferably of cylindrical form and reduced on opposite sides of its upper end, so as to form horizontal shelvesa a' on the main Water-chamber. Water is supplied to the water-chamber through a filling-tube a2, which yextends downwardly into the waterchamber through the shelf a and is normally closed by a screw-cap. It is necessary t'o leave a clear space in the' top 'of the waterchamber in order to permit the water therein to rise and fall as the pressure of the gas varies. When lling the' water-chamber through an ordinary opening in the top, .it is Serial No. 23.645 ACNO model.)

difficult to determine when the'water has reached the desired level. In order to enable the attendant to readily observe the height of the water when the sameirises. to the desiredwlevel, the illing-tubev a2 is extended vdownwardly into the water-chamber and terminates with its lower end at a point in line with the normal level to which the waterchamber should be filled with water. he attendant when filling the' water-cha ber can distinctly observe the water as it enters the lower end of the-filling-tube and so determine when the water has reached the properlevel. L

B represents a purifying-chamber containing water or other purifying solution or liquid through which the gas is passed for purifying and cooling-the same. This chamber is arranged in the upper contracted part of the waterLchamber'fand is supplied with water througha filling-tube h, which is arranged above the shelf a' and which is normally closed by a screw-cap, as shownpin Figs. 2 and 4. It is necessary to leave a clear space in the purifying-.chamber above the water .therein to collect the gas which passes upwardly through the water in the chamber. In order to prevent the attendant from filling the purifying-'chamber too high with Water, the filling-tube b opens with its outlet end into the lower part of the purifyingphamber I and extends'with its inlet end upwardly to a point in line with the normal level to which the purifyingchamber should bey filled with 'D represents the carbidor generating cham-` ber, which is arranged below the regulatingchamber and which receives the charge of calcium carbid forming part of the gas-producing material. The water from the waterchamber passes downwardly through a verti IGC ca l pipe d, connected at its upper end with the bottom of'the'water-tan'k, thence into a sediment-chamber d', connecting with'the` lower end ofthe pipe d, thence upwardly through a main pipe d2, connected at its lower end withthe sediment-chamber, thence down-v wardly through a'vertical pipe d3, which is arranged within the main pipe cl2 and coinmunicates with the same at its upper end, thence upwardly into the equalizingchamber through a pipe d4, which connects at its lower end with the lower end of- Ithe pipe da and at its upper end with the regulating- .chamber, as shown in Fig. 'l'.

E represents a stand-pipe which extends through the watexwcham'ber and into the purifyingehamber and which opens at its upper end above thewvater-level in the purifying# chamber. rf f y e represents the casing of a valve whereby the water is turned'- on or off from t-hcgenerati-ng-.chamber-. A'lhis casing'is arranged ceutrally in theequalizing-charnber and is provided with 'a vertical delivery -passage e', which connects the lowereud of the standpipe with the generating-chamber, and a lat# eral regulating-passagee2, which connects the v lower end Aof the stand-pipe with the upper part of "the equalizing-chaunber.Y Normally the water passes from the equalizing-chamber upwardly through the lateral passage e2 in the valve-casiugand risesin' the stand-pi pe.

e3 is the rotary plug of the valve, whichis arrangedin' the vertical passage .c and is provided with the usual transverse port, whereby upon turning the -plug ,the vertical passage may be opened or closed. The plug of the valve is arranged onv a horizontal valvestem e4, which extends laterally through a supporting-sleeve e5 on the valve-casing and is held in place by a gland e6, screwed into the sleeve and bearingrv against a collar or shoulder@7 on the valve-stem, and a .jam-nut e8 onthe gland bearing against the supportingesleeve. v y y v F represents an upright gas-delivery pipe, which extends with its lower end through thel eqi'laliziug-chamber and opens into the up-.

per endy of the generating-chamber, while its upper part extendsthrough the water-chamber andinto the purifying-chamber-and terminates 'at its open upper end above the water in the purifying-chamber. Upon turning the valve-plug e3 so as to open the passage e of the valve-casing the water in the vstandpipe dropson the carbid in thegeneratingchamber,- and the generation of gas takes.

place.

The gas passes from the generating-chamber upwardly through the gas-pipe F and into L a dome f, which is arranged above the upper end of the gas-pipe. .This dome is closed at- ,the top and open at the bottom and hasI its,A lower open end submerged in the water of the.,

puiifyingjchamber, asshown in Fig. 1.l Thev gas passes downwardly through the dome and discharges from the lower end of the latter into'the water of the purifying-chamber and then passes upwardly through the water into the upper .part of the purifying-chamber. While the gas passes through the water any moisture, dust, dirt, or other impurities coutaiued in the gas are removed or washed outof the same and the gas is als@ cooled, thereby improving the quality of the gas and avoiding the liability of clogging the pipes through which the same passes. The lower or discharge end of the dome is provided with an annular horizontal langef which causes the gas as it issuesfrom the bottom of the dome to be spread out over a considerable area,

thereby subjecting thel same Yto a more 'thorf ough washing action. yThe purifying action The upper part of the dome is comparatively large, while the lower part is contracted, as vshown in Figs. 1 and 2. j By' this means the outlet for the gas at the lower end of the dome 'is reduced and -brought close to the delivery-pi pe F, whereby the danger of dashing much water into the upper end of the delivery-pi pe is reduced when the lamp is upset. Another advantage resulting'- from the contraction of the lower end of the deine is that it reduces the surface area of the water or other Aliquid in the purifying chamber' which is exposed to the carbid 'throughthe gas-pipe,therebyred ucing the liability of gen.; eratin g gas by the 4moisture or' dampness which is afforded by the exposed liquid-surface'in the purfyiugchamber. Furthermore, by thus contracting the outlet'of the do'me this outlet is vbroughtnear the center et` the dome, which location is' above the. water-line ft on oi" the purifying-'chamber when the lamp falls to one side, thereby reducingthe possibility-of water entering the carbid-chamber V'through the delivery-pipe F. The upper or enlarged part of the dome forms a trap which'catches' the water which may pass into thesanie from the purifying-chamber .when the lamp falls on its side, aud thus prevents the water from passing through the 'delivery-pipe into thecarbid-chamber. The gas passes from the top of the purifying-chamber through a discharge v or burner pipe G tofa burnerpg, where it is consumed. Some of: the gas passes from the upper end of the purifying-chamber int the top of vthe standpipe and presses downwardly against the column of water in the in the stand-pipe varies and-is governed by the pressure of the gas.. -When the normal Y. same. The heightl of the column of water generation of gas takes place andthe gas is consumed or 'delivered as fast as the same is generated, water is present in the stand-` pipe and passes from the latter through the valve and upon the carbid inthe generating-chamber, whereby the generation of gas is maintained. If an abnormal quantity oi gas is generated, the pressure of the accumulating gas causes the water in the standpipe to be pressed. downwardly ,by the gas entering the top of the stand-pipe. lf the production of an excessive amount of gas continues, the increasing pressure of the gas causes the column of water in the stand-pipe to be pressed downwardly until the level of the water is below the inlet of the passage e' in thevalve-caslng, whereby the supply of water to the carbid-chamber is automatically cut olf andthe generation of gas ceases as soon as the water previously delivered tothe carbid has been spent. The water which has been displaced' from the stand-pipe by the downward pressure of the gas first passes through the lateral'passage e2 into the equalming-chamber, thence downwardly through the pipe d4, thence upwardly through the pipe d, thence downwardly throughthe pipe d2 and into the sedimentchamberd, and thence upwardly through the pipe d into the water-chamber, in which the level of the wateris raised correspondingly. As the surplus gas is consumed the pressure of the same is gradually reduced, which causes the water to gradually return from the water-chamber through the pipes' d didi d* and chambers d' and C and enter the stand-pipe and carbidchamber, and then the generation of gas is resumed.

lf the generation of gas continues for a considerable time after the water has been automatically cut od by the downward pressure of the gas in the stand-pipe, the increasing pressure of the gas causes thesame to enter the equalizing-chamber through the passage e2 and displace the water in the same.

This chamber is comparatively wide" and shallow, so that a considerable amount of gas can take the place-of' thelwater .in this chamber without materially varying the level or height of the water,` thereby maintaining a practically-uniform pressure of the gas and causing the flame to burn uniformly. If an unusual amount of gas is generated by reason of an excess supply of water and the pressure of gas continues tov rise after the water sin the equalizing-chamber has been displaced by gas, this increasing pressure of the gas causes the same to follow the water downwardly through the pipe d4, thence upwardly through the pipe cls, and thence outwardly to the atmosphere by a vent-pipe h, which connects with the open upper end of the pipe d2. The vent-pipe preferably extends upwardly through the water-chamber and terminates with its outlet end around the burner, as shown in Figs. 1, 2, and 3, whereby the gas escaping through the ventpipe is ignited by the llame at the burner. It will thus be seen that the rise and fall in the pressure of gas causes the water to pass serves as a safety means tol effectually prev vent .the passage of any gas to the waterchamber, where its accumulation is liable to produce disastrous results.

When it is desired to extinguish the dame, the valve is closed, thereby cuttingoif the supply of water from the stand-pipe to the carbid-chamber. By arranging the watervalve immediately at the place where the water is. delivered to the carbid-chamber this valve when 'closed cuts the supply of water off positively and` immediately -from the carbid, so that the generation of gas is practically stopped at once'and no water canenter the carbid-chamber if the lamp is lshaken while handling the same. A

By locating the valve es inthe branch passage e free communication .is maintained at all times between the lower end of the watercolumn and the water-supply below the same. If. the valve is turned ed immediately after an excessive amount of water has been deliveredtothe carbid, the excessive amount of gas resulting therefrom causes the water to be pressed downwardly in the water-co1- umn and into the equalizing-chamber by rea- IOO son of the free communication between the same, thereby preventing undue pressureof the gas at the burner and maintaining a uniform dame.

The size of the passage e' is very small compared with the size of the water-column, this passage being just large enough to supply the maximum amount of water to the carbid. By thus restricting the size of the feed-passage e' relative to the water-column it causes the water which is not carried to the carbid by the passage e to rise in the water-column.

When the gas-pressure 'is high, the-watercolumn ,is pressed from the top down, which causes the reduced weight or pressure of the water resulting from the reduced height of the water-column to flow less rapidly upon -the carbid.

` When the pressure or amount of gasis reduced by consumption, the water -column rises and the dow of water t the carbid increases by reason of the increased weight or pressure of the higher column of water, thereby increasing the generation of gas.

It will thus be seen that by restricting the water-passage e', leading from the water-co1- unn to the carbid-chamber, an automatic regulation of the water-feed is obtained,which is as positive as a partial closing of the valve es and is due to the rising of the water more or less in the column above the inlet of the feed-passage e';

' The liquid in the purifying-chamber in addition to purifying and cooling the gas which Ilo e in producing afine regulation of the water.- f

lssues from the generating chamber also serves asa liquid seal or column-which aids supply to vthe carbid. Inasmuch as the gas from the carbid-chamber is obliged to pass through the column of liquid in thepurify.-` ing-chamber before it reaches the gas-space in the purifying-chamber, the pressure ofthe gas in the latter chamber is lower thanthat in the carbid-chamber; pressure against the lower end of the liquid column in the stand-pipe to preponderate over the gaspressure against the upper end of the liquid column in the stand-pipe. By

this means the weight of the regulating liquidy column in the stand-pipe is offset Vand the flow ofliquid from the stand-pipe into the carbid-chamber is retarded notwithstanding that the liquid'in the stand-pipe is above the feed-opening, thereby producing a very close regulation or governing of the liquid-supply to the carbid and still permitting the size ofy the feed opening or passage e to-be made large enough to avoid clogging. v

The sediment which is precipitated by the water in the sediment-chambermay be removed from the ylatter by detaching its botable quantity of water from the Watercha1n ber'when the, lamp is upset or handled carelessly.'

vJ "represents an upwardly tapering' or con` ical guard-cap which is secured-to the upper end of the stand-pipe and which is provided at its apex witha small opening j and projects with its edge j' beyondthe side of the stand pipe. The opening j isV suieiently largeto permit the gas topass freely into and out of the top of the Vstand-pipe as thepressure of the gas varies, but is s o small that' when the lampis upset or handled carelessly no appreciable quantity of water can pass throughV this opening from the purifying` As thewater chamber intothev 'standpipe l e e dashes about in the purifying-chamber when handling the lamp carelessly the water strikes 'against the' under side of the overhanging edgeof-'th'e cap on the stand-ppe,' whereby the breaking of the water over the top of the' cap is checked. "Anyvwater that may dash or break over'the top of the cap'is shed by the inclined' side Vot thev cap'when the lampis rghted.

from passing trom the Vpurifyin g-chamber into the generating-chamber,-the upper end of the gas pipe is provided with av trap chamber, which is constructedwas follows:

l K represents a'guard or trap chamber ar-. ranged between the top of the gas-pipe F and the dome f. .This chamberis secured with the upper edge ofv its side wall to the dome and its'with its inner edge over the top of the gas-pipe. The bottom of the guard-chamber is formed by two reversely-inclined cones 7a 7.a',l which are connected at their lower ends and form togetheranL annular channel or trough around the upper end of the gas-pipe. y

The bottom of the channel or trough isprovided with an' annular row of small 'openings .792, through which the gas passesdownwardly from the gas-pipe into the water, but which prevent anyconsiderable quantity of water passing from the dome into thegas-.pipe and 'to the carbid-chamber. The inclined under the same to be deiiected away from the opening in the bottom of theftrough.` Anywater that may pass into the trough, if the lamp remains upset for some time, is again drained by the inclinedsides -ofthe troughto the openings thereof and discharged into the purifying-chamber when the lamp is righted. The 'guard-chamber K is fitted loosely on ltop l of the gas-pipe, and the screen f2 rests loosely onthe bottom of the puritying-chamber, so

as to permit these parts, together with the dome, to' be removed for cleaning the lamp or repairing the same. Access is afforded to the inside of the pirifying-ehamber through an openingin the topt thereof, which opening is large enough yfor the passage of the dome o vand connecting partsand is normally closed by a plate k3, whichis connected with the top of the purifyinggchambe'rby a packed screwjoint 7a4, asshown in Figs. k1 and 3. A

In order to preventthe'escape of any (Sonj-V siderable quantity of Water 1into the 'burnerpipe G when the lamp is upset or handled carelessly,the lower or inlet end ofthe burnerjpipe isinclosed by a guardfor trap chamber 'L, having a topi, secured-to the inletV end lof the delivery-pipe, 'anda bottom,'consisting of In" order "to vprevent any considerable quantityot water -side'ot' the trough` causes Athe waterstriking IIO two rever'sely-inclined cones Z' Z2, whichform is provided with' perorations, which IJertnit the gas to pass from'the purifying-chamber tothe burnerpipe andwhichprevent the water ofy thepurifying-chaxnber from escap is upset.

Thebott-o'm of this troughHA .ing rapidly into -the delivery-pipe if the lamp l s o or trap chamber L is drained back into the purifying-chamber by the inclined sides of its conical bottom when the lamp is turned right side up. The upper guardchamber L is preferably mounted on thecover-plate k3, s o as to be removable therewith. The burnerpipe is composed of an upper fixed section Z3 and a lower movable section Z4. These are connected by a union Z", which permits the lower section to be removed, together with the upper guard-chamber L and cover-plate k3, when access is desired to the interior of the purifying-chamber.

When a small charge of carbid was placed in the carbid-chamber. of an' acetylene-geni erator as hereinbefore constructed, suiiicient gas would have to be generated to fill the va- 'cant space in the carbid-chamber before the gas would reach the burner, which was objectionable, because the lamp was not ready for immediate use whenfthe charge of .carbid was placed in the generating or carbid chamber. In order to secure a prompt supply of gas at the burner when using a small vcharge of carbid, a hollow air-tight filling-piece M is placed in the bottom of the carbid-chamber. This filling-piece takes up the space which otherwise would be occupied by the'balance of a full charge of carbid and causes the gas as soon as it is generated to pass immediately to the burner, so that the lamp is ready for use when charged. A number of these tilling-pieces of different sizes may beprovided, so as to 'permit of using varying charges of carbid.

The generating-chamber is detachably connected at its upper end with the under side of the equalizing-chamber by a screw-joint n, which is provided with a packing n', whereby the generating-chamber may be removed for charging 'the same. As shown in the drawings, the vent-pipe Vh, trap-.pipe d, stand-pipe E, and gas-pipe F serve as a supporting connection between the water-chamberand equal izing-chamber. The lamp is supported while in use'by a main base N, which is arranged on the lower end of the generating-chamber and is removable therewith, In order-to provide a support for the upper part of the lamp containing the water-supplying device 'and other parts while the generatingchamber and base are removed, a subbase N' is provided, which is arranged around the lower part of the generating-chamber and the main base when the parts are assembled and which is connected at one side'with the lower ends of the pipes forming the double trap or seal. The opposite side of the subbase is preferably connected with the upper parts of .the lamp by a brace or standard fn?. The generating-l chamber is preferably provided with an annular Iiang'e n3, whereby it bears against the upper inner side of the subbase, and the main base is provided with an annular shoulder n4, whereby it bears againstv the lower inner side of the subbase, as shown in Figs. 1- and 2.

I thas been found in practice that the genber upon lowering the same.

eration of gas continues a short time after the water has been turned off from the generating-chamber bythe valve, which causes thediame to'burn until thesupply of gas is consumed, and therefore prevents the dame from being extinguished at will. In order to permit of instantly darkening the room in which the fiame continues to burn after the water is turned o, a darkening-hood O is provided, which can be moved so as to expose the flame or to conceal the flame from the side. When the lamp is in use, this hood is lowered around the water-chamber, so asl to expose theburner above the hood, in which position the latter is supported by an internal flange o' at the upper end of the hood bearing' against the upper part of the lamp, as shown by dotted lines in Fig. 1 and in full lines in Figf2. When it is desired to conceal the dame, the hood is raised into the position shown in full lines in Fig. 1, whereby the burner is inclosed from the side and the llame is concealed. The hoodis held in thisl position by two lugspp, arranged on oppositew sides of the upper part of the body or the water-chamber of the lamps and engaging between an internal annular dange p on the lower end of the hood and two locking-pro-f jections p2 p2, arranged on the inner side of the hood, above the annular lower ange p'. The hood is raised while its projections p2 p2. are arranged vertically out of ,line with the lugs p jp of the water-chamber until the latter .are engaged by the lower flange p of the hood. The hood is then turned until its pro'- jections p2 have been moved over the lugs of the water-chamber, which prevents the hood from descending while in this position. The -entrance of the 4.lugs on the water-chamber into the space between the lower flange and the locking-projections of the hood is facilitated by beveling or iuclining the front end of each projection, as shown at p5, Fig; 6, and the turning movement of the hood on the lng p is arrested when the par-ts are properly en gaged by a shoulder' or stop p4, arranged on the rear end of each projection p and engaging against-the adjacent s'ide ot' the companion lugp on the water-chamber, as shown in Fig. 6. The locking-projections on the IDO IID

hood are preferably formed by pressing the same out of the body of the hood. When the hood is lowered, its lower iiange iits around the upper part of the equalizing-chamber, as shown in dotted linesl in Fig. 1 and in full lines in Fig. 2, thereby holding the hood in place. This flange dares downwardly, so as to guide the hood upon the equalizing-cham- If desired, a globe or shade may be mounted on top of the hood, so as to shade the light when the hood is in its lowered position.

In the modified construction of my .improved acetylene-lamp shown in Figs. 7 and 8 the purifying-chamber and the parts ar ranged therein are omitted. In this construction t-he gas-delivery pipe F' is connectcdat its uppeuen'd by an inclinedl section` g directly-.with the yburner-pipe G', and-the upperendlot the'standfpipe E' isi-connected with the burner-pipe and gas-pipe by-a trapchamber R; `This chainberfis provided atits' ing conical. heads r rl, which are. .perforated 'i at their lowest parts.. -The gas from the; pipe F'v passes down-wa'rdl y through the chamber R` and acts upon the top .of vthe :column of,
